Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505056, here are decompositions:

17 + 31505039 = 31505056
29 + 31505027 = 31505056
53 + 31505003 = 31505056
113 + 31504943 = 31505056
173 + 31504883 = 31505056
257 + 31504799 = 31505056
353 + 31504703 = 31505056
389 + 31504667 = 31505056

Showing the first eight; more decompositions exist.
